// NcPlane
//
/// A drawable [`Nc`][crate::Nc] notcurses surface, composed of [`NcCell`]s.
///
/// Unites a *CellMatrix* with an *EgcPool* (a matrix of `NcCells` with a pool
/// of extended grapheme characters).
///
/// `type in C: ncplane (struct)`
///
/// # About planes and piles
///
/// A given notcurses context is made up of one or more piles.
///
/// A pile is made up of [`NcPlane`]s, totally ordered on a z-axis.
///
/// You can't manage the piles directly, but only the `NcPlanes`.
///
/// A pile is destroyed when all its planes are destroyed or moved to other
/// piles.
///
/// A pile has a top and bottom plane (this might be a single `NcPlane`),
/// and one or more root planes (`NcPlane`s which are bound to themselves).
///
/// Multiple threads can concurrently operate on distinct piles, rendering or
/// mutating it, while another thread concurrently renders or mutates another.
///
/// Each `NcPlane` is part of one and only one pile. By default, an `NcPlane` is
/// part of the same pile that contains the `NcPlane` to which it is bound.
///
/// When an `NcPlane` is created without being bound to another `NcPlane`, then
/// it becomes the root plane, top, and bottom of a new pile. As a root plane,
/// it is bound to itself.
///
/// A new pile can also be created by reparenting an `NcPlane` to itself,
/// though if the plane is already a root plane, this is a no-op.
///
/// When an `NcPlane` is moved to a different pile (whether new or preexisting),
/// any `NcPlane`s which were bound to it are rebound to its previous parent.
/// If the `NcPlane` was a root plane of some pile, any bound planes become root
/// planes. The new `NcPlane` is placed immediately atop its new parent on its
/// new pile's z-axis.
///
/// When [`NcPlane::reparent_family`] is used, all `NcPlanes` bound to the
/// reparented `NcPlane` are moved along with it. Their relative z-order is
/// maintained.
//
/// Rendering reduces a pile of `NcPlane`s to a single `NcPlane`, proceeding
/// from the top to the bottom along a pile's z-axis. The result is a matrix of
/// [`NcCell`]s. Rasterizing takes this matrix, together with the
/// current state of the visual area, and produces a stream of optimized control
/// sequences and `EGC`s for the terminal. By writing this stream to the
/// terminal, the physical display is synced to some pile's `NcPlane`s.
///
/// [`NcPlane.render`] performs the first of these tasks for the pile of which
/// the plane is a part. The output is maintained internally; calling `render`
/// again on the same pile will replace this state with a fresh render.
/// Multiple piles can be concurrently rendered.
///
/// [`NcPlane.rasterize`] performs rasterization, and writes the result to the
/// terminal. It is a blocking call, and only one rasterization operation may
/// proceed at a time.
///
/// It is necessary to call `NcPlane.rasterize` to generate any visible output;
/// the various *output calls* only draw to the virtual `NcPlane`s. Most of the
/// notcurses `statistics` are updated as a result of a render, and screen
/// geometry is refreshed (similarly to [`Nc.refresh`]) following the render.
